DidiWiki is a small and simple Wiki implementation. It's intended for personal use for notes, Todo's, etc. It runs a browser via a local server. It was original written by Matthew Allum with updates from Peter Korsgaard and Amigo.

DidiWiki stores its data in text files located (by default) at /root/spot/.didiwiki
This is inside the savefile on frugal installations.
To save the data elsewhere move the .didiwiki folder to the desired location, then symlink that directory back to /root/spot/.didiwiki. Note the directory may be hidden in some file-managers including RoxFiler
